I! '1 all whom it may concern.

Be it known that I, (Jnauencn J. EVANS, a citizen of the United States residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Mop-Wringers, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings.

This invention relates toa mopwringer of that type wherein there is a readily portable tank adapted to contain liquid associatcd with a pair of rollers at the topof the tank which are separable to allow the insertion of the mop and may then be brought together under spring pressure to enable the rollers to coact and squeczethe liquid from the mop as the rollers are rotated. The objcct. of the invention is to simplify and cheapen the construction, providing a device which is at the same time efficient, in expensive and d'urable. The characteristics of the invention will. be best understood from the following description of an ap proved form thereof with the summary of essential features appearing in the claims.

In the drawings, which show an approved form of my wringer, Figure 1 is a side clevation of the wringer in position for use; Fig. 2 is a side elevation of the upper portion of the device with the rollers Separated, showing the bail in position for carrying the device; Fig. 3 is a vertical cross section showing the machine in positionfor use; Fig. 4: is a plan of the device; Fig. 5 is a detail in vertical section through the bearing of the shiftable rollen The tank, as shown in the drawings, is a rectangular wooden receptacle consisting of four sides 10, 11, 12, and 13 held together by bolts 14- and nuts 15, and asuitable bottom 16. 17 indicates supporting rollers at two of the corners at the bottom and *18 feet at the other two corners, This construction, however, may he varled as desired.

At the top of the two sides 10 and 12 are frame castings 20 secured in place by two of i the bolts 14. At one end these castings have downwardly extending cars 21 overlapping the side members 10 and 12, the. upper through-bolt extending through these cars. At the other side the wooden Wallis extends between the castings to the top thereof and the upper bolt on that side extends through the main portion of these two castings and intermediately may occupy. a groove in the outer face of the board 1 3. These castings 20 provide. the support for the roller mechanism which will now be described.

30 indicatcsthe non-shifta'ble roller. This is mounted on a shaft 31 which is journaled in the two castings, these castings being provided with bosses 23 on their inner faces to provide suitable bearings. Beyond one of the castings 20 the shaft 31 is provided with a crank 32 by which the device is operated. Between the crank and frame casting this shaft carries a gear 35. This gear meshes with an idler 36 secured to a stud 37 mounted on the tank member 10, and this idler 36 meshes with another idler 38 secured to a stud 39 mounted on the frame member 10. The other roller is adapted to be geared with and driven by this latter idler, as will be presently explained.

The shiftahle roller is designated 10 and is mounted on a shaft 41 which extends loosely and slidably through slots 28 in the castings 20, and beyond one of these castings carries a gear 43 which is adapted to mesh, when the device is in operative position, with the idler 38.

designates a suitable bail, which, adja-v cent to its ends, is formed into housings 51 which extend about the shaft 41 between the roller 40 and the frame castings 20. In the recess of each of these housings is a block 53 hearing against the shaft tl and pressed in that direction by a compression spring 55 which stands within the housing and has its ends surrounding bosses 56 and 57 on the bail and bearing block respectively. At the upper rear portion of each housing on the bail is formed an car 59. This car is pivoted to a link 60 by means of a bolt 61. The link is offset outwardly so that its other end lies close to the inner face of the frame casting 20. At this point the link is pivoted to the casting by bolts 63.

When the device is in the position shown in Fig. 2 the bail extends approximately vertically and may form a convenient handle for carrying thedevice, and in this position of the parts there is ample room between the rollers for insertion of the mop into the liquid in the tank. When it is desired to wring the mop the bail is depressed and this forces the shiftable roller into coaction with the non-shiftable roller. The parts are so proportioned that the shiftable roller may contact with its mate before the bail is horizontal and accordingly the furroller, each roller having an operating shaft,

ther downward movement of the bail after such contact compresses the springs (the end of the bail moving toward the bearing of the non-shiftable roller) and establishes the desired spring pressure between the rollers.

Before the bail reaches its horizontal position in contact with the top of the wall 11 the piv'ots 61 of the links 60 have been carried below the plane connecting the other pivots of these links with the axis of the shiftable roller. The result is that a dead center has been passed and thesprings reacting tend to force the bail downwardly and thus hold it in position, maintaining the rollers under spring pressure. The device thus provides a very effective toggle whereby a strong spring pressure may be easily applied to the mop and automatically maintained. 1

It is understood that when the bail is depressed the gear 43 comes into mesh with the idler 38 so that thereafter the crank may rotate the two rollers in relatively opposite directions to wringthe mop. To prevent the material of the mop being entangled either in the shiftable mechanism or the bearings of the non-shiftable roller I provide suitable guards, as the metal straps 70, which are shown as located within the tank a short distance from the walls 10 and 12. These straps are preferably sheet metal members secured at one end to the walls mentioned and then having an inwardly extending portion and then a portion parallel with these walls, the straps at their ends being at right angles and secured to the wall 13.

It will be seen that my mopwringer is simple in construction and provides the very desirable characteristics of a readily portable device adapted to have a large open space for the insertion of the mop into the liquid and be immediately set to put the mop under a strong spring pressure with the rollers geared for wringing action by the crank. As the gear 4:3 passes tangentially into mesh. with the idler 38tl1ere is no danger of its being blocked by the ends of the teeth abutting each other. 7

Having thus described my invention, what I claim is g 1. The combination with a stationary frame of a noneshiftable roller, a shiftable a bail having slotted portions extending around the shaft of the shiftable roller, bearingblocks for the shiftable roller slidably mounted in the slots of said slotted portions, springs in said slots bearing against said blocks, and links connecting the, bail to a stationary frame.

3. The combination, with a receptacle, of a pair of frame members at the top thereof provided with slots, a shiftable roller hav ing a shaft extending through said slots, a bail having its arms extending between the ends of the shiftable roller and the frame members, the end portions of the arms pro viding slotted portions surrounding the shaft of the shiftable roller, compression springs mounted in said recesses and bearing against said shaft, links connecting the bail with stationary points to provide a toggle action, and another roller with which the shiftable roller may cooperate under such spring toggle action.

The col bination of frame members provided with guiding slots and stationary bearings, a shaft journaled in said bearings, a roller on said shaft, another roller having a shaft extending through said slots, a bail having its arms extending about the shaft of the last mentioned roller between the roller and frame members, said arms having elongated slots Where they extend around said shaft, blocks in the slots bearing against said shaft, compression springs in the re cesses bearing against the blocks, and means pivotally carrying the bail. V
